Wheel engraved by Jacob Sang (Amsterdam) with clasped hands emerging from clouds with a crown above and cornucopia either side.The reverse is inscribed by Sang with a poem written (c. 1740) by Dirk Smits Gedichten of Rotterdam:MIND GY EDELE VRIENDSCHAP TEEDER (If you value tender, noble friendship) VULD MY DAN TOOT AAN DEN RAND (Then fill me to the brim) DRINKT MY LEEG, AND VULD MY WEEDER (Drink me empty and refill me) STELD MY ZOO UW VRIEND TER HAND (And thus hand me to your friend).There are around six recorded examples of Friendship glasses with the Smits poem engraved by Sang, although this example is the only one so far to be found with its original cover. A rare survivor in all aspects.
